Some Samsung smart fridges stopped working on Tuesday due to a firmware update.
Korean outlets were the first to report the problems, which affect Samsung’s Bespoke AI line of fridges. Star News Korea, per a Google-provided translation, said that most of the affected devices were four-door fridges from 2024 or later.
The only reason I can think of why a fridge should be connected to WiFi is to notify you if the door is left open, or the temperature is too high.
